Features Make sure that the oscilloscope is connected to the power outlet. Wait a few seconds for the filament to warm up and cast a bright spot on the screen. Locate the knob that adjusts the brightness, and make the spot visible, but not too bright, by changing the intensity of the beam.
Input Amplifiers The input stage of the oscilloscope is used to couple the signal of interest to the input amplifiers, needed to increase the signal amplitude to a level appropriate to drive the electron beam deflection circuitry.
It provides a known, regular waveform by which the oscilloscope may be calibrated to ensure that subsequent readings are accurate. The calibration signal, shown in Fig.
Push in the adapter plug and twist until it locks in place thus the "bayonet" action of the "B"NC and connect the hook tip of the probe to the BNC signal.
In general, both leads of the scope probe would need to be connected to measure a potential difference. However, since the signal is derived from the oscilloscope itself, the ground reference is already present and no additional connection is required; generally an additional connection would be made between the black banana clip of the probe and the ground of the circuit being measured.
While using the probe in this exercise, please ensure that x1 sensitivity is Oscilloscope lab report on the probe handle.
Adjust the vertical position of the trace to an easily remembered position on the display, generally the axis of the reticle. Now move the slide switch to the DC setting. If the sensitivity is set to 0. If not, see your lab instructor for assistance. Draw the waveform seen on the display and record the voltage from top to bottom of the square wave.
To take a voltage reading: Take readings at several sensitivities; discuss which provides the greatest accuracy. Ensure that the outer sensitivity knob, which provides a variable gain if needed, is in the CAL position fully clockwise and in the detent position before making the readings.
The difference between dc and ac coupling can be understood by examining Fig. As you will see later in the course, the capacitor shown in the ac stage prevents the average dc voltage from reaching the CH1 amplifier.
Determine the average dc level associated with the CAL signal by switching between ac and dc coupling and observing the change in the vertical level of the trace. The real utility of ac coupling becomes apparent when trying to measure small variations "riding" on a sizable dc level.
With dc coupling, increasing the input sensitivity in an attempt to see the small variation will send the trace off the top of the screen.
Use a BNC-banana adapter; this adapter is color-coded, red for the signal input and black for the ground reference presumably 0. With dc coupling, first confirm that the output voltage of the power supply is correct.
If you then try to examine the ripple more closely by increasing the sensitivity, the trace is soon driven off the edge of the display. With ac coupling, the dc level is suppressed and the ripple can be observed in detail; measure its amplitude and compare to the dc level.
Trigger Control The triggering circuitry is the means by which the oscilloscope is able to provide repeated "snapshots" of a repetitive signal.
Oscilloscope Lab Introduction: The purpose of this lab is to introduce students to the basic tools used by engineers and technicians in analyzing electronic equipment: the function generator, the analog oscilloscope, and the digital. Conclusion: In this lab we used the oscilloscope to measure the current of several simple circuits. The oscilloscope let us actually see the current going through our setup and allowed us to manipulate it to acquire values and a different perceptive of this flowing energy. Through this lab we slowly figured out how to properly use this machine and 92%(25). Record these observations in your lab report. B. Lissajous Figures If the sweep function is disabled, and instead another sinusoidal voltage is connected to the horizontal motion, interesting curves appear that are called Lissajous figures.
By controlling the threshold voltage of triggering and slope polarity, the user is provided with great flexibility in the appearance of the display and the utility of the scope for capturing elusive signals.Oscilloscope lab report, the oscilloscope lab report, oscilloscope lab report essay, oscilloscope calibration lab report, physics oscilloscope lab report.
